BRUSH.

SPECIFICATION forming part of Letters Patent No. 661,358, dated November6, 1900.

Application filed June 22, 1900.

To f/,ZZ whom it may concern:

3e it known that I, MAURICE RosnNTHAL, a citizen of the United States,and a resident of the city of New York,borough of Manhattan, in thecounty and State of New York, have invented a new and Improved Brush, ofwhich the following is a full, clear, and exact description.

The purpose of this invention is to provide means for increasing theelasticity or life of a paint,varnish, kalsornining, or like brush andalso to provide means for bridling the bristles. It is known thatbrushes of this sort require bridling to enable the bristles to beproperly controlled. This is generally done by tying a string around thebristles just below the ferrule. It is also known that brushes are bestwhen the bristles are long, thus giving elasticity or what is known topractical men as life to the brush. I attain these ends by fastening aflexible center piece to the brush within the mass of bristles and tyingthe bristles snugly around the center piece.

This speciiication is the disclosure of one form of the invention, whilethe claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a perspective view of the invention. Fig. 2 is a sectionalview thereof, and Fig. 3 is a view of the resilient center piece which Iemploy.

In Figs. l and 2, a represents the handle, h the ferrule, and c thebristles, of a brush, all of which are arranged in the usual manner. Thelower end of the handle ct is tapered and is driven into the ferrule, inwhich the bristles have already been placed, thus securelyholding thebristles in the ferrule. Within the upper part of the ferrule a block hof wood is fastened.

In carrying out my invention the tapered lower end of the handle a isformed with a slot a', and in this slot isiitted the shank-like portiond' of the center piece CZ. This center piece may be formed of a sheet ofany resilient material. Now it is clear that when the handle is driveninto place the walls of the slot a. are forced against the shank d ofthe Serial No. 21,188. (No model.)

center piece, and the center piece is held securely in connection withthe handle. The main part of the center piece extends below the fel-rulel) and is situated centrally with respect thereof, so as to passdirectly through the bristles, dividing them into two parts. The sideedges of the center piece are formed with serrations cl2, and these sideedges project just beyond the side edges of the brush. I now pass thebridle cords or wirese around the bristles, engaging the bridle wires orcords in the serrations d2 of the center piece, so as to hold the cordsin place. The result of this construction is that the brush is not onlybridled, but considerable resiliency is lent to the bristles by theresilient center piece, which is situated inside of the brush and hasthe bristles on either side. The invention is especially useful inconnection with flat brushes,such as paint or kalsomining brushes, inwhich the bristles are generally inclined to collect in separate tufts,thus rendering the brush inefficient. By the application of my inventionthe bristles are held in proper adjustment and the efficiency of thebrush much increased.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A brush, provided with a resilient center piece heldin the bristles and dividing them into two parts, and a bridle-cordpassed around the bristles and engaging with the edges of the centerpiece.

2. A brush provided with a center piece located between the bristles,and a bridle-cord or the like passed around the bristles and engagedwith the edges of the center piece.

3. A brush, provided with a center piece having a part fastened to thehandle of the brush inside of the ferrule, the center piece lyingbetween the bristles, and a bridle-cord passed around the bristles andengaged with the edges of the center piece.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

MAURICE ROSENTI-IAL.
